Loom PATTERN MECHANISM.

SPECIFICATION forming part of Letters Patent No. 524,372 dated August14, 1894.

7 Application filed November 16, 1893 Serial No- 491,173. (No model.)Patented in Engl ancl November 17, 1891, No. 19,906,

To all whom it may concern:

Be it known that we, ROBERTS BEAUMONT,

professor of textile industries, and GEORGE WASHINGTON, assistantlecturer, both of the Yorkshire college of the Victoria University,

I subjects of the Queen of Great Britain and 12,502,-bearing date June26, 1893,) of which the following is a specification.

Our invention relates to improvements in the mechanism for regulating orcontrolling the movement of the levers for actuating the warp and forcontrolling the motion' of the shuttle boxes and picking arms, wherebythe pattern in the woven cloth is produced; and is equally applicablefor operating dobbies or engines in which bowls and bushes, or lags andpegs, are at present employed.

The object of our invention generally is the construction of the saidmechanism in such a manner, that the necessary alterations for producinga fresh design can be readily-and rapidly performed, or moreparticularly, so that any one or more of the lifting pieces or strikers,(hereinafter for the sake of brevity referred to asstrikera) can bereadily moved round from an operative to an inoperative position withoutdisturbing the adjacent pieces or strikers.v We attain this object bythe mechanism illustrated in the accompanying drawings, in whicht Figure1 is adiagrammatic side view of one arrangement of loom patternmechanism'to which our invention is applied. Fig. 2 is a detailed planor face view to a larger scale of aportion of our-improved patternchain. Fig.

- 3 is a side view of the chain with parts in secthe'cross rods 11. Fig.10 is a view of the chain driving cylinder, the section of which alongthe line V V or T T is shown more clearly in Fig. 3. Fig. 11 is a planview and Fig. 12 aside elevation of an end of the framey showing thecantalever upright 11. formed with a V recess or supports 3 s to receiveand carry the ends of the fixed rods.

In the said drawings a a designate one pair of levers connected with thehealds for moving the warp. These levers are hinged on the fixed'centerb, and are moved in one direction or the other by means of theconnecting link a from the toothed disk crank d,according as the tootheddisk cl is in gear with the toothed wheel (or cylinder) e, orf. The

toothed disk 01 carried at the free end of the Vibratinglever g (hingedon the fixed center it), is thrown into gear with wheel eby riding thetop of one of the strikersmof the pattern chain was; or with wheel fwhen the striker is reversed, allowing the lever g to drop into theposition indicated by the dotted line. The pattern chain is actuated'bypassing over the rotating fluted cylinder 1'.

j is a stretching or weight cylinder. Our invention refers to theconstruction of the pattern chain at a: and the chain driving cylinder11, and may be applied to other arrangements of mechanism than thatabove described, which hasbeen added merely for the sake of generalillustration and reference.

The strikers m m consist of small castings, or sheet metal (punched andbent to shape), of approximately triangular or other shape to suit theparticular loom, having oblong holes with semi-circular ends. Thestrikers for the sake of likeness are formed hollow and the oblong holesare preferably lined with a thin strip of sheet metal 41. n, whichextends therefrom to regulate the distance apart sidewise of thestrikers and to provide bearing surface for the rods 70 and The rods Zmay be plain cylindrical, but are preferably made oblonginv section asillustrated for the sake of strength.

If the removable rod is withdrawn from any row of strikers, thecorresponding ends of the strikers will all. hang down from the other,fixed, rod, and any one of the strikers may be lifted up until the fixedrod is at the opposite end of the oblong hole, and the striker is thenreversed and allowed to hang down. (Or the striker may be first reversedabout the fixed rod, and then allowed to drop until the fixed rod is atthe opposite end of the oblong hole.) In this manner any one or more ofthe strikers may be reversed without detaching the rest. Whenthereversal is completed, the removable rod is reinserted, and the endsof the same coupled up to the adjacent rod of the chain by the links 0.

The links 0 may be kept in place on the fixed rodsby means of holes andsplit pins. To lessen the trouble and time required for connecting anddisconnecting the links, our invention comprises the improved linkconnection shown in the accompanying drawings. This consists in turningor forming a recess 10, Fig. 7, on the fixed rod about the middle of thelink end, slitting the upper side of the corresponding (cylindrical) endof the link,

aforesaid recess 19. The end of the spring 4" j is allowed to projectslightly, so that the spring can be readily lifted out of the recesswhen it is desired to remove one of the side links preparatory towithdrawing one of the removable rods.

In order totake the strain between the vi- Zc and Z, we form thestrikers with projections q, and the chain driving cylinder 1' withshoulders or ridges it, having corresponding beveled edges or restingfaces to, on which the projections (1 rest.

To facilitate the alteration of the pattern chain, we provide a flatrectangular bar or frame 1 the length of the same being suited to thewidth of the chain. The frame y is provided at each end (see Fig. 11plan and Fig. 12 side elevation) with a cantalever upright u formed witha V recess or supports 8 s to receive and carry the ends of the fixedrods. The bed or frame y is also provided with a groove 1;, running itswhole length, in which groove the projections q of the strikers fit. Ondetaching the link 0 the row of strikers with the fixed and removablerods is transferred to the frame, the ends of the fixed rod resting onthe V supports .9 s and the projections q of the strikers in the groove2). k removable rod Z is then withdrawn, and any one or other of thestrikers can be lifted and reversed in the manner above described,with-.

out disturbing any of the other strikers. The removable rod is thenreplaced, and the row of strikers can be returned to the chain.

Having fully described our invention,what we claim, and desire to secureby Letters Patent, is

1. The combination of lifting pieces or strik ers m, having oblongholes, with two rods Z0 and Z, the latter of which is removable, passingthrough each hole which is adapted by its oblong shapeto allow thereversal'of one or more of the strikers, when rod Z is removed, withoutdetaching the rest, and side links 0 connecting the ends of the saidrods with the ends of the adjacent rods of the next adjacent rows ofstrikers respectively, the whole combination forming a pattern chainsubstantially as set forth.

2. The combination of lifting pieces orstrikers m, having oblong holes,with two rods and Z, the latter being removable, passing V through saidholes, which are adapted by their i Oblong shape to allow the reversalof one or 1 more of the strikers, when rod Z isremoved in the manner andfor the purpose set forth.

brating levers g and the strikers m off the rods 3. The connecting links.0 provided Withon the said rods, substantially as and for the purposesset forth.

4.. The lifting pieces'or strikers m, having oblong holes andprojections q and distance pieces a, lining the oblong holes of the saidstrikers and extending laterally therefrom, substantially as set forthor shown, for the purposes specified.
